Abstract

The invention provides a durable and hardly-deformable polyethylene wood-plastic composite. The hardly-deformable polyethylene wood-plastic composite comprises the following components: by weight, 100-150 parts of high density polyethylene, 30-40 parts of polyvinyl chloride, 10-20 parts of chlorinated polyethylene modified polyvinyl chloride, 10-20 parts of an epoxy resin, 5-10 parts of coumatone resin, 3-6 parts of butyl rubber, 5-10 parts of polyacrylamide, 5-10 parts of boric acid alkylolamide, 2-4 parts of dioctyl sebacate, 10-12 parts of tricresyl phosphate, 3-8 parts of polyester imides, 10-20 parts of epoxidized soybean oil, 5-10 parts of vaseline , 10-15 parts of polyvinylbutyral resin, 50-80 parts of a wood flour, 10-20 parts of zinc oxide, 10-15 parts of figuline, 5-10 parts of lithopone, 3-15 parts of calcium carbonate and 5-8 parts of a glass fiber. The hardly-deformable polyethylene wood-plastic composite has the advantages of good mechanical properties, hydroscopicity of 0.3% or less, tensile strength of 15MPa or more, and heat deformation temperature of 115DEG C or above. After destruction by high temperature and high humidity, deformation rate of the hardly-deformable polyethylene wood-plastic composite is less than that of contrast products.

Description

[0001] technical field [0002] The invention provides a wood-plastic material, in particular relates to a durable and non-deformable polyethylene wood-plastic material, which belongs to the technical field of polymer materials. [0003] Background technique [0004] Wood-plastic composite (WPC) is a new type of composite material that has been booming at home and abroad in recent years. It refers to the use of polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC) to replace the usual resin adhesives. More than 50% of wood flour, rice husk, straw and other waste plant fibers are mixed into new wood materials, and then processed by extrusion, molding, injection molding and other plastic processing techniques to produce boards or profiles. Mainly used in building materials, furniture, logistics packaging and other industries. The plastic and wood powder are mixed in a certain proportion and then extruded to form a board, which is called an extruded wood-plastic ...
